The League Against Cruel Sports' chief executive Douglas Batchelor said the proposal to ban hunting had moved from being a cruelty issue to "a matter of trust between the Government and the voters".
The Hunting Bill was left out of the Queen's Speech, despite calls from the RSPCA, the League Against Cruel Sports and the International Fund for Animal Welfare for its inclusion.
But Peter Hain, Leader of the House of Commons, assured MPs it would be reintroduced in the new year. The Prime Minister also told the Commons that he supported Hain's comments: "We will resolve the issue this Parliament," he said.
The three groups released the results of a Mori poll last week showing that 76 per cent of people think hunting with dogs should not be legal.
